Robotic assisted treatment of flank hernias: case series

Flank hernias are uncommon, surgical treatment is challenging and the minimally-invasive approach not always feasible. The aim of this study was to report the safety and feasibility of the robotic-assisted repair.

The study was approved by the local ethic committee (2019-01132 CE3495). A retrospective search on a prospectively collected dataset including demographic and clinical records on robotic surgery at our institution was performed to identify patients treated for a flank hernia. Patients were followed-up 6 months.

From January 2018 to December 2019, out of 190 patients who underwent robotic-assisted hernia surgery, seven with incisional flank hernia were included. Median age was 69.0 years (IQR 63.2-78.0), BMI was 27.3 kg/m² (IQR 25.8-32.3) and two patients were male (29%). All patients were referred to surgery because of pain, whereas one of them described recurrent episodes of small bowel obstruction. The median hernia defect measured 25 mm ((IQR 21-40), median mesh diameter was 10 cm (IQR 10-12.5) and median operative time was 137 min (IQR 133-174). No intraoperative complication occurred. Postoperatively, one patient developed a pneumonia, which required antibiotics. Length of hospital stay was 4.0 days (IQR 3.0-7.7). Six months after surgery, neither recurrence nor chronic pain were recorded.

Robotics in abdominal wall hernia surgery remains a matter of debate, despite a growing interest from the surgical community. In our reported experience with flank hernias, we found the robotic-assisted approach to be safe and feasible for the treatment of this uncommon clinical entity.
